A single mom lost over 40 percent of her body weight in a single year for the sake of her sons.

Jane Morgan of Essex, England weighed 392 pounds when doctors said she wouldn’t live to see Callum, 8, who is severely disabled, or Connor, 10, into their teenage years. The death sentence scared her into revolutionizing her life, including seeking gastric bypass surgery.

Morgan is now 200 pounds lighter and 16 dress sizes slimmer. The 38-year-old mom attributes all her success to wanting to care for her boys, especially Callum. He suffered brain damage at birth and requires 24-hour supervision.

“I was very frightened. It would fall to my parents to care for Callum, and they are in their 60s now. It wouldn’t be fair. The boys make everything worth living for,” Morgan told SWNS.com.

Morgan has another reason to celebrate—a unique diary of photos documenting her dramatic weight-loss achievement. She had a photographer friend take a photo of her every few months, but she refused to look at them until a year passed this September.

“I was totally gobsmacked when I first saw the end result,” Morgan said. “I can’t really believe it’s me.”
